RATCHET- WRENCH.

SPECIFICATION forming part of Letters Patent No. 763,105, dated June 21,1904.

Application filed September 10, 1903. Serial No. 172,656. (No model.)

T0 ari/ZZ 14177/0171, it Wto/,y concern.'

Beit known that I, BYRON H. MORRISON, a citizen of the United States,residing at Bradford, in the county of McKean and State of Pennsylvania,have invented a new and useful Ratcliet-VVrench, of which the followingis a specification.

This invention relates to ratchet-wrenches, and has for its object toproduce a simply-constructed and easily applied and operated device ofthis character which may be employed upon any form or size of nut andwhich may be adjusted to enable it to be used in' cramped and confinedlocalities inaccessible to wrenches of ordinary construction.

To this end the invention consists in certain novel features ofconstruction, as hereinafter lshown and described, and specified in theclaims.

In the drawings illustrative of the invention, in which correspondingparts are denoted by like designating characters, FigureV 1 is a `sideview with one of the handle-sections removed. Fig. 2 is a longitudinalsectional view. Fig. 3 is a side elevation of the socket memberdetached. Fig. 4 is a side view of the socket member in section on theline 4 4 of Fig. 3. Fig. 5 is a plan view, on a reduced scale,illustrating a modification in the construction. Fig. ,6 is a side viewof the form of structure shown in Fig. 5. Fig. 7 is a perspective Viewof the adjustable jaw member detached. v

The improved device consists of a handle portion comprising two parts1() 11, one part having projections 12 and the other part havingcorresponding cavities 13 to receive the projections, so that when thetwo sections are united, as by bolts or rivets 14, they will be iirml ysupported from lateral' strains and their relative displacementprevented. y

Each of the handle-sections is provided with a parti-circular recessembraced by segmental lhorns 15 16 17 18, the two cavities beingdisposed in alinement transversely of the handle-sections when thelatter are united, as shown.

Formed within the handle-sections parallel with and concentric to thecurved faces of the parti-circular cavities are ribs 19 2O andcorresponding adjoining channels 21 and 22, as

indicated in Fig. 2, and in the inner faces of Vas a whole at 27) formedto correspond to the cavities and rotative therein and provided `withribs 28 and corresponding channels 3() and intermediate ratchet-segment32, the channels 3() for engagement bythe ribs 19 20 and the channels 2122 for engagement by the ribs 28, while the ratchet-'segment 32v is forengagement by the pawls 25, as shown. By this arrangement it will beobvious that when the parts 10 11 are united with the socket member 27in position in the alined parti-circular cavities and the correspondingribs and channels interengaging and the pawls operatively engaging theratchet-segment the socket-member is free to rotate in one directionrelative j to the handle-sections, but will be held from turning in theopposite direction.

It will be noted that the cavities embraced by the horns 15, 16, 17, and18 are more than one-half of a circle, so that the socket member cannotbe withdrawn when the handlesections are clamped together. .A

The socket member 27 is formed with a square or rectangular centralcavity for en-v gagement with the nut.

To enable the socket member to be adapted to nuts of different sizes, amovable jaw member 33'is arranged within thesocket and adjustabletherein.

To provide for the. adjustment of the jaw 33, thebottom of thenut-recess is provided with a cavity in which an arm 34 on the jaw 33 isslidably disposed, as by guide-ribs 35 and guide-plates 36 37, thelatter attached, as by screws or other means, tothe' socket member. Thelower side of the arm 34 is provided with aplurality of spacedratchet-teeth with which a spring-controlled pawl 38 engages, the pawl,mounted ona transverse shaft 39, mounted for rotation in the socketmember 27 and operative from the outside thereof IOO by finger-disks orbuttons 40, as shown. By this arrangement it will be obvious that thejaw member 33 may be moved transversely of the socket-cavity and heldrigidly at any desired point, and thus adapted for any required size ofnut.

In Figs. 5 and 6 the handle member is provided With a joint Il to enablethe socket end to be turned at an angle to the body of the handlemember, as shown in Fig. 6, which Will be required when the implement isto be used in cramped or confined localities, and adds materially to thevalue and efliciency of the invention.

A spring-catch 42 is shown attached to the device at the hinge to holdthe parts in their different positions.

The parts Will be formed of metal, preferably of steel, and may be ofany size required and may be varied in minor particulars withoutdeparting from the principle of the invention or sacrificing any of itsadvantages.

That I claim is l. A ratchet-wrench comprising' a handle dividedlongitudinally and with aparti-circular cavity in each portion anddisposed in transverse alinement when the portions are united, each ofsaid handle portions having a rib and channel concentric to its cavity,a socket member mounted for rotation in said cavities and having ribsand channels for engagement with the ribs and channels in said handleportions, and formed with a lateral guide\vay, a movable jaw-sectionhaving an arm engaging said guideway, and provided with a plurality ofspaced transverse teeth, a pawl carried by said socket member forengagement with said teeth, and means for rotating said socket memberand its attachments, in one direction by the intermittent movement ofsaid handle member, substantially as described.

2. A ratchet-Wrench comprising a handle divided longitudinally and witha parti-circular cavity. in each portion and disposed in transversealinement when the portions are united, one oi' said handle-sectionshaving spaced cavities and the other with corresponding spacedprojections engaging the cavities, and each of said handle portionsprovided with a rib and channel concentric to its cavity, and a socketmember mounted for rotation in-said cavities and having ribs andchannels for engagement with the ribs and channels in said handleportions, and means -for rotating said socket member in one direction bythe intermittent movement of said united handle portions, substantiallyas described.

In testimony that I claim thc foregoing as my own I have hereto aiiixcdmy signature in f the presence of two Witnesses.
